Definition: The word "old" in Greek has various meanings, but generally means "in old age." In Hebrew, it refers to those who have reached maturity, especially as defined in the Torah. For example, Old Testament, Old Testament refers to Old Covenant or covenant era, and Old Age refers to the period of human existence before Adam and Eve became human. Old Age also refers to the period after death, where humans return to their former bodies, and life begins again (Genesis 2:17).
